Schizophrenia is often associated with a high level of the neurotransmitter dopamine.
Dopamine

Parkinson's disease is characterized by a lack of dopamine in the brain due to the degeneration of dopamine-producing neurons. Therefore, treatment with dopamine medication helps to alleviate the motor symptoms associated with the disease by increasing dopamine levels in the brain.
Dopamine receptor agonists are a type of medication that activate dopamine receptors in the brain. They are often used to treat conditions such as Parkinson's disease, restless leg syndrome, and hyperprolactinemia. By mimicking the effects of dopamine, these drugs help improve symptoms associated with these conditions.
